ctk-transitions — animation playground + code generator for your CTk apps

[kandelucky]

Hi all 👋

I just published a tool that might be useful if you've ever wanted to add
nice animations to your CustomTkinter apps without writing tween logic
from scratch.

ctk-transitions is a standalone playground that lets you pick an
easing curve and a duration, then watch the animation run on six widget
categories — buttons, cards, text, loaders, popups, and toasts. When you
find the combination you like, hit Generate code and you get a
self-contained .py module that wraps everything you need to drop the
animation into your own project.

What's in the generated code

• The easings you actually used (no dead code)
• A small Tween class (~30 lines, time-based at ~60 fps via after(16ms))
• Helper functions (lerp, color interpolation if needed)
• The animation function itself
• A runnable if __name__ == "__main__" demo

So the output stays dependency-free beyond customtkinter — no extra
libraries, no pip subtree, just paste-anywhere Python.

Quick start

pip install ctk-transitions
ctk-transitions          # launch the GUI
# or
python -m ctk_transitions

Links

• PyPI: https://pypi.org/project/ctk-transitions/
• GitHub (screenshots + per-tab GIFs): https://github.com/kandelucky/ctk-transitions-code-generator

The 9 easings included: linear, ease_in, ease_out, ease_in_out,
ease_out_quint, back_out, elastic_out, spring, bounce_out —
the usual set from easings.net references.

Happy to hear feedback or feature requests, and if anyone's tried
similar things, would love to see what you've built.

(This started as a tool window inside
CTkMaker, a visual designer
I'm building for CustomTkinter — figured the playground was useful
enough on its own to publish separately.)
